Years ago, there was a website with free study guides for all or most of the books of the Koine NT. They were written for 2nd year Koine students, I think. Is the site still around?
I found them in case anyone is interested.

I’m really glad they are still around. It’s amazing how much from the very early 2000’s and even the 1990’s is still around.
